Dreiherrnspitze, Mountain summit in Venediger Group, Austria-Italy border.

Dreiherrnspitze is a mountain summit on the Austria-Italy border with an elevation of about 3,500 meters (11,500 feet). The peak features several glaciers and presents multiple climbing routes that vary in technical difficulty.

The first documented ascent was made on 2 November 1866 by guide Balthasar Ploner with Michael Dorer and Isidor Feldner, via the southwest ridge. Earlier claims of an 1861 ascent during the land survey by the Berger brothers of Prägraten are considered dubious. The exposed east ridge was first climbed in August 1902 by Thomas Maischberger and Paul Gelmo, and the northeast face on 25 August 1926 by A. Hein and Karl Schreiner.

The name, recorded as Dreyerherrnspitz in 1501 and Drey Herrn Spiz in 1770, refers to the three lords whose domains met here: the Prince-Bishops of Salzburg, the Counts of Tyrol (alternating with the Bishops of Brixen), and the Counts of Gorizia. A local tradition also links it to the Heilig-Geist-Kapelle in Prettau, whose Trinity dedication is called "pa di drai Heang" in South Tyrolean dialect.

All routes to the summit are glacier crossings requiring rope, crampons and experience. From South Tyrol the normal route starts at the Lenkjöchlhütte and leads over marked paths to the Hinteres Umballtörl at 2849 m, with a short secured rock passage. On the Austrian side the Clarahütte at 2036 m, open since 1872, serves as a base.

The mountain marks a rare point where Salzburg, Tyrol, and South Tyrol meet at the summit, making it a triple-border peak. This geographic coincidence draws mountaineers who appreciate standing at the exact meeting point of three regions.
